At present, we expect that the 2500 rpm limit to be enabled during the field test.February 13, 2019
In order for the device to provide continuous output power of 500W the motor would need to run at around 3750rpm. (Power of the electronic load = Xrpm/3000rpm *40V*10A). What is the purpose of the …February 13, 2019
Are there specific simulation and experimental results that should be provided in the progress report or we should enclose the most striking ones based on our own choice?
Will there be a more detailed description of the required contents of the progress report as there was for the Design proposal or will there not be anymore updates on the document which contains guidelines …February 13, 2019
It would be reasonable to assume that the hot spot and case temperature test would be performed with the device running at maximum continuous output power of 500W, but it has been stated that the …February 13, 2019
What is meant by “enter fault mode” at free acceleration test (most recent Technical Reference Document 22f)?
It has not been specified what’s supposed to happen in the fault mode. Should we turn the device off when the speed reaches 2500rpm or just prevent the device from working at speeds above 2500rpm? …February 13, 2019
When the fault conditions are reached, the system will have to provide an indication should be made as required in the technical reference document item 14.E. How the system responds to the fault event to …February 13, 2019
With a selected output power as specified under 22.b.iii and the specified speed limit of 2500rpm there is a maximum output power (of the electronic load) which can be calculated as 2500rpm/3000rpm*40V*Iout. The throttle signal …February 13, 2019

In the provided IFEC Workshop agenda it is stated that the workshop takes place on the 17th of March. In the post about announcement of the second round competition teams it is stated that the …February 13, 2019
Hello, IFEC 2019. I would like to do an early registration to attend the IFEC workshop at APEC 2019. However, I have difficulty in selecting the registration type. I would like to get information about …February 1, 2019
The Technical Sheet specifies a Target Box Volume of 1500 cm^3. We were wondering if this was an upper bound or if the box needs to be relatively close to this volume. We also noticed …February 1, 2019
Is it input or output? In what form? It is an output from the box that simply provides voltage sense terminals of the battery, which will be connected to a voltmeter or a display unit …February 1, 2019
Should we overload the motor above the given nominal current even though in the Technical reference document it is said that extended continuous and sustained operation outside the given ratings will lead to increased temperature rise and should be avoided?
In the given Technical reference, the requirements for the continuous power rating of 500W (requirement no.2), nominal voltage, current and frequency (requirements 5a, 5b, 5c), and over-speed limit (requirement no.18) are given. In one of …February 1, 2019
In the technical reference, the requirements of the continuous power rating of 500W (requirement no.2), nominal voltage, current and frequency (requirement no.5) and speed limit (requirement no. 18) were given. In the previous question, you …February 1, 2019
In the most recent technical reference, the over speed limit is listed as 3000 rpm while the loaded acceleration test listed the maximum testing speed TBD. The question is when to expect the maximum testing speed requirement and whether it is 3000 rpm or not.
These items have been clarified further in the updated technical document.February 1, 2019
Will the qualified teams receive comments on the submitted proposals ? Anonymous comments from first round review can be provided each team upon request by e-mail from the IFEC 2019 General Chair. Moreover, will there …February 1, 2019
The Request for Proposal mentioned financial support for travel expenses. How does the money transfer procedure look like? Is it necessary for the teams to submit an request letter or something similar?
Travel reimbursement guidelines are posted here.February 1, 2019
Yes. Travel reimbursement guidelines are posted here.February 1, 2019
Which results should we provide in the report for the Second Round Competition? What is the deadline for sending the report and is there a specific form of the report that is required?
These are specified here and the updated technical reference document.February 1, 2019
